Just that. I have been on the highest dose of wegovy for ages had lost 4 stones but really need to lose two more.
I found the highest dose was no longer working and old cravings etc were reappearing.
So under the guidance of my prescriber I changed to mounjaro obviously on the 2.5 dose to begin with .
I have gained about 5 pounds in one week!! I have been counting calories but obviously I'm in a panic as I really cannot return to the old me!
Has anyone else made the swap? What is your experience if you did?

It’s probably water weight as the medication interacts differently with your body than the previous one. I highly doubt you’ve gained five pounds in a week unless you have been inhaling pizza on a daily basis.

Thankyou I
I'll just carry on definitely not having the same effect as when I started ozempic.

The 2.5mg dose is just to give your body time to adjust to the new medication. You may get more suppression at 5mg though some people don't and need to go up to 10, 12.5 or 15 to get the desired effect. Just stick with it.

Did you have to come off Wegovy for a month before starting Mounjaro? If so how did that go?

stealthsquirrelnutkin · 12/04/2025 16:55

Nope, I'm with Voy and they sent a 2.5mg pen to arrive in time for my next weekly injection. I think the advice to wait a month has been changed.

2.5mg didn't do much for me. You definitely need to increase your dose

Sorry just saw these replies - thankyou.
No my prescriber ( Boots) said one week break was sufficient but I actually took over two weeks.
Really struggling on this dose but onwards and downwards I hope
I've also got a fractured ankle which is a bit of a problem

So if you took 2 weeks break, the level of wegovy would be very low and mounjaro 2.5mg is a low dose starting off. As you go up pens you will hopefully get better suppression. Drink plenty of water and focus on protein. Limit carbs as they cause water retention.
For me I needed 10mg as I have unstable blood sugars with insulin resistance.
